First, limp-wresting will never cause a fail-to-extract problem where the extractor is slipping off the case rim with the case still in the chamber.

And I seriously doubt a F&B is going to fix it either, although polishing the chamber might be a good idea.

Most likely cause is a loose extractor spring screw.

Ask your gunsmith guy to de-grease the threads with solvent and put it back together with Blue Loctite.
That will most likely cure the problem.

NO, the spring isn't fragile at all.
I have never heard of one breaking or wearing out.

The problem comes if you don't hold firm pressure on the plastic grip on each side of the pin when you pry it out.

The spring sets in a pocket milled in the side of the aluminum frame, and is only held in place by pressure from the side of the plastic grip.

If you try to pry the pin out with no grip pressure, it will flex away from the frame and allow the spring to slip out of place.

When you take the pin out, squeeze the frame between your thumb and fingers and then kind of "wiggle" the pin until the spring works it's way up out of the groove in the pin.

If you pry it out with one fell stroke, the grip may flex and let the spring pop out of place.

Once you get the hang of it, you can take the gun apart all you want without hurting anything.
